Oxygen[ edit ] Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around kPa psi , [1] [2] or in the UK and Europe, bar approximately psi. In areas where a bulk system or high-pressure cylinder manifold is not suitable, oxygen may be supplied by an oxygen concentrator.

However, on site production of oxygen is still a relatively new technology. Medical air[ edit ] Medical air is compressed air supplied by a special air compressor , through a dryer in order to maintain correct dew point levels , and distributed to patient care areas by Half Hard BS: In smaller facilities, medical air may also be supplied via high-pressure cylinders.

The neutrality of this section is disputed. Relevant discussion may be found on the talk page. Please do not remove this message until conditions to do so are met. January Learn how and when to remove this template message On rare occasions, bleed air used for air-conditioning, and pressurization can be contaminated by chemicals such as oil or hydraulic fluid.

While those chemicals can be irritating, such rare events have not been established to cause long term harm. This alleged long-term illness is referred to as Aerotoxic Syndrome by agenda groups, but it is not a medically recognized syndrome. One alleged potential contaminant is tricresyl phosphate. Many lobbying groups have been set up to advocate for research into this alleged hazard. Cabin Environment Research is one of many functions of the ACER Group, [12] but their researchers have not yet established any causal relationship.

A verification of cabin air contamination with toxic substances e. Recent improvements in solid-state electronics have enabled pneumatic power systems to be replaced by electric power systems. In a bleedless aircraft such as the Boeing , each engine has two variable-frequency electrical generators to compensate for not providing compressed air to external systems.

A ton of them! The point behind using supports is to put the guitar into an optimal position for ease of playing but also to allow for correct posture and a physically healthy playing style. Having one foot up on a foot stool can strain the back, leg, and neck muscles. The Ergoplay device fastens on via suction-cups.

Hook-up drawing indicates tubing slopes, position of instrument in reference to process tapping point, scope break between instrument vs piping. Hook-up drawing also gives information the requirement of bulk material for each installation. It also details its specification size, type and material and the quantity. There are two types of hook-up drawing: Process Hook-Up This hook-up drawing contains typical installations for instrument which connects to the process Pneumatic Hook-Up This hook-up drawing contains typical installations for instrument which requires instrument air such as control valve, actuated valve Reference drawing: A good designer can also read whether the instrument tapped in gas service or liquid service.

My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”? I had previously suspected that some tadpoles are late undergoing metamorphosis, but this one really missed the boat.

Pneumatic systems like the oleo strut generally have long operating lives, and the construction is not unusually complex for maintenance purposes.. An oleo strut consists of an inner metal tube or piston, which is attached to the wheel axle, and which moves up and down in an outer (or upper) metal tube, or cylinder, that is attached to the airframe.

History[ edit ] Cleveland Pneumatic Tool Company designed and introduced the first oleo-pneumatic shock-absorbing strut for airplanes, later called “Aerol” struts in The cavity within the strut and piston is filled with gas usually nitrogen, sometimes air—especially on light aircraft and oil usually hydraulic fluid , and is divided into two chambers that communicate through a small orifice. When the aircraft is stationary on the ground, its weight is supported by the compressed gas in the cylinder.

It compresses the gas, which acts as a spring, and forces oil through the orifice, which acts as a damper. A tapered rod is used on some designs to change the size of the orifice as the piston moves, providing greater resistance as compression of the strut increases. Additionally, a check valve is sometimes used to uncover additional orifices so that damping during compression is less than during rebound.

Nitrogen is usually used as the gas instead of air, since it is less likely to cause corrosion. The various parts of the strut are sealed with O-rings or similar elastomeric seals, and a scraper ring is used to keep dust and grit adhering to the piston from entering the strut. In this application, an engine driven pump is used to pressurize the hydraulic fluid.

The Quadro range of motor scooters use the oleo strut to allow for low speed lean.

These isolate tubing from its supports, Beware of Tubing Vibration! It is suggested that impulse lines for instruments shall be arranged to avoid: When tube vibration is a problem, due to the closeness of machinery, process pressure changes or other excitation, it is recommended: The orientation of the loop should be chosen with due regard to the probable relative motion between the connections.

These units provide consistent high quality welds when operated correctly. Plastic Instrument Tubing Ensure that extremely soft plastic tubing is used with an insert. Never use metal ferrules on plastic tubing. This technical article includes important subjects such as Ferrule hardness, 2. Pipe and Tube – Lots of very useful information here including descriptions on seamless and welded, common pipe and tube terms, manufacturing methods, nominal working pressures, pipe dimensions and weights, tube weights and working pressures.

Edraw allows you to more easily create piping and instrumentation diagrams for piping systems, industrial, chemical, fluids and hydraulics drawings. It is used by people in a variety of crafts. The primary users of the document after plant startup are process technicians and instrument and electrical, mechanical, safety, and engineering personnel.

So you can always have it ready to hand, the Illustrated Professional Dictionary of Horology is also available in a paper version. Containing around pages, it lists nearly terms in four languages (French, German, English and Spanish), with an alphabetical index.

Other documents used in the development of the CSS configuration are as follows: The usual appearance of them is to have the cause on the left hand side with the effect at the top with a ‘X’ matrix. Sometimes logic symbols are included which make the operator’s engineering design requirements unambiguous. Whilst this is an excellent approach it is rather costly, thus it is infrequently used. Cause and Effect – Some projects categorize cause and effects as part of process document and some other projects consider them an instrument deliverable.

Cause and Effect is presented as a form of matrix. The marked intersection between both means that they are related as cause-effect. Example Cause and Effect – A useful example of an Cause and Effect diagram – from instrumentationportal. This package is deliberately separate from the executive software of the system since it is very important that software previously developed is not corrupted in any way. After completion the software is tested extensively before being included in the overall software package.

Great emphasis is placed on ensuring that the executive software cannot be accessed by unauthorised personnel and once the system is operational the configuration package is usually located onshore. It is all very well to have duplicated and triplicated hardware but if there is a common software bug just what can be done to overcome the problem.

Well the answer is that the requirements of API RP14C should be followed in that there should be a primary and secondary safety system. Usually the primary being the electronic system and the secondary, safety relief valves.
